What number when divided by one will you have a remainder of one when divided by 2 3 4 5 6 7 8 or 9?
(2 x 3 x 4 x 5 x 6 x 7 x 8 x 9) + 1 will have a remainder of 1 when divided by 2, 3, 4, 5, 6, 7, 8, or 9. (2 x 3 x 4 x 5 x 6 x 7 x 8 x 9) + 1 = 362,881
What is 8.478 in expanded in form?
8.478 = (8 x 1) + (4/10) + (7/100) + (8/1000).
How do you write 8759 in expanded notation?
Expanded Notation of 8,759 = (8 x 1,000) + (7 x 100) + (5 x 10) + (9 x 1)
What is x squared-7x equals 8 factored?
x2 - 7x = 8 x2 - 7x - 8 = 0Now find two numbers that multiply to equal -8, and add to equal -7.(1) * (-8) = -8(1) + (-8) = -7(x+1)(x-8) = 0 This is the factored form of x2 - 7x = 8You can then solve the equation if necessary, and get:x = -1 or x = +8
What equation has a solution of 9?
Of course, x-1=8 is a solution. Any equation which results with the variable value as 9 is ur answer. For eg: x = 9 / x-9 = 0 1 - x = -8 / x-1 = 8 x-2 = 7 / 2-x = -7 Any, any such equation will be your answer(correct answer). Enjoy
What are the 2 solutions for x plus 8 equals 1?
There's only one solution. [ x = -7 ]
What is the answer for x -8 equals -1?
-7
What is y equals 3x minus 7 and y equals negative x plus 1?
y=3x-7 y=-x+1 We're looking for when their x=x and y=y, so set the problems equal to each other. 3x-7=-x+1 3x+x-7=x-x+1 4x-7=1 4x-7+7=1+7 4x=8 4x/4=8/4 x=2 Let x=2 and solve for y in one of the equations. y=-(2)+1 y=-1 The solution is:(2,-1)
How do you solve 8 plus x equals 7?
8+-1= 7 x=-1
The sum of two integers is -8 and their product is plus 7 what are the two integers?
short answer -1 and -7 long worked answer let x = one of the integers let y = the other integer x+y = -8 xy = 7 solve for y y = -8 - x plug y in x(-8 - x) = 7 rearrange -x^2 - 8x - 7 = 0 divide both sides by -1 x^2 + 8x + 7 = 0 factor (x + 7)(x + 1) = 0 x = -1, -7 y = -8 - x so y = -8 + 1 = -7 or -8 + 7 = -1 so when x = -1, y = -7 when x = -7, y = -1
How do you make 8 using only numbers 2 5 7?
One solution is, 7 + (7/(5 + 2)) = 7 + 1 = 8. Or, 2 + ((5 + 7)/2) = 2 + 6 = 8. Or, (7 x 5) - 27 = 35 - 27 = 8. Or, 2(7 - 5) x 2 = 22 x 2 = 8 No doubt there are many other solutions.
How do the numbers 5 8 7 and 1 equal 24?
8 x [1 + (7 - 5)] = 8 x [1 + 2] = 8 x 3 = 24
X minus 8 equals negative 1?
If X - 8 = -1 then X = -1 +8 Therefore X = 7
What is the hydronium ion concentration of a solution at 298 K whose hydroxide ion concentration is 1 x 10-8 A 1 x 10-6 B 1 x 10-7 C 1 x 10-8 x D 1 x 10-14?
The answer is A 1 x 10^(-6)
What is one eighth x seven?
1/8 x 7 is 7/8
What are the points of intersection when the line y -x equals 7 spans the curve y equals 8 over x on the Cartesian plane?
If: y -x = 7 Then: y = 7+x If: y = 8/x Then: xy = 8 Therefore it follows that: x(7+x) = 8 So: 7x+x^2 = 8 => 7x^2 -8 = 0 Using the quadratic equation formula: x = -8 or x = 1 By substitution the line intercepts the curve at (-8, -1) and (1, 8)
